n ml 1 n i I 4 v n u a r I I I I A N w Patented Aug. 26, 1930 1 UNITED STATES PATENT OFFICE mIBERT H. MOSS, OF BROOKLYN, NEW YORK, A S BIGNOR '10v THE LINDE AIR PRODUCTS COMPANY, A CORPORATION 01 OHIO COLUMN CONNECTION This invention relates to building construction', and more particularly to an'improved method of and means for securing structural steel members to tubular and other structural 5 steel columns.

Heretofore, tubular structural shapes'and columns have not been extensively used in steel building construction because, in joining or attaching floor beams, girts or roof 1() trusses to such shapes and columns, special castings or intricate attachment means have been used. These are unsatisfactory, principally because their use involves considerable expense and they are of doubtful structural merit.

The principal object of this invention is to provide a more practical and acceptable methor of attaching lateral members to tubular shapes so as to permit a more general useof such shapes in composite building structures. Other objects of this invention are to provide a joint construction in which the joints to be welded are disposed so that parts may be conveniently united b oxy-acetylene, electric are or similar welding; to provide a joint which does not weaken the structure to which it is applied.

The above and other objects and the'novel features of this invention will be apparent from the followin description taken with the accompanying drawings, in which Fig. 1 is a horizontal sectional view of a tubular column having structural members securedthereto at several points, in accordance with the principles of this invention; Fig. 2 is a side elevation of a portion of the tubular column of Fig. 1

Fig. 3 is a sectional view taken along the line 33 of Fig. 2, looking in the direction of arrows; and I Fig. 4 is a sideview of a column having a truss gusset plate secured thereto, in accordance with the principles of this'invention.

Broadly speaking, according to my invention floor beams, girts, roof trusses'and similar lateral members may be secured'to tubular building columnsby metallic wing plates appropriately welded to such columns. I preferably employ connectors or wing plates in the form of angles having unequal legs,

and cut openings or slots in the wall of the column to receive the shorter legs which are welded at their edges to edges of the slot. Each slot is of suflicient width so that a pair of wing plates may be welded therein back to back and spaced apart to receive between them a portion of the structural member which is firmlysecured to such plates.

Referring particularly to Fig. 1 of the drawin s, the tubular column T has two I beams and A and a gusset plate G secured thereto by joints which are similar to one another,-so only one will be described in detail in order to avoid duplication and confusion. At the point selected for the attachment of the lateral member, the column is provided with an opening or slot S, as by cutting out a section of the tubular wall with an oxyacetylene torch. Portions of suitable wing plates are welded into the slot S and their outwardly projecting portions are spaced apart a sufficient distance to receive between them a part of the structural member, which is secured to such plates by bolting, riveting or welding or any combination of these. It is desirable that the edges of the wing'plates which are to be welded to the edges of the slot shall be isolated from the bases of the plates where the latter contact the wall of the column, so as to enable easy manipulation of the welding blowpipe or arc and produce better Welds, and to avoid unbalanced metal areas at the points of welding. I I therefore preferably use wing plates in the form of metal angles, such as the angular plates M and N, which are disposed back toback and separated by a space K that is sub-. stantially radial to the axis of the tubular column. The angles M, N desirably have legs of unequal length, the shorter legs M N fitting flush intothe slot S and having edges thereof butt welded to edges of the slot, as by fusion deposited metal forming welds W, W. The legs M, N are of sufficient Width to isolate the welds from the planes of the longer legs I M", N and thereby greatly facilitate the a through registering openings formed in the web and Wing plates prior to assembly.

By means of my improved joint the load on the lateral member is transferred to the column through welds which primarily function in shear in resisting the applied loads on the Wing plates and in tension in resisting the vertical column loads tending to spread the column at a point of lateral connection. The strength of the column at the point of lateral connection is improved by reason of the added metal introduced by the wing plates, which are in the plane of the wall oi the column and serve as stiiieners or supplementary columns at such points. The column may be prepared and equipped in the shop with such apertured wing plates, according to specifications, thus leaving for field work only the assembly thereon oi the lateral members.

This improved method of construction pro vides a means for lateral approachment to a column from one or more points in the same horizontal plane; and, in addition to I beams, numerous other structural members may be joined to a column in accordance with the principles of this invention. For example, by means of a gusset plate G, the heel of a root truss comprising members It and B may be mounted upon the upper end of a column, as shown in igs. 1 and l. Openings or slots S, S are provided in diametrically opposite sides of the column and pairs of angle wing plates C and D are welded into such openings in the manner already described. Such slots may extend downwardly from the upper end of the wall of the column, and a portion of the gusset plate projects into these slots between the pairs of wing plates and through the axis of the column. The inserted part of the gusset plate may also rest upon the lower ends of the slots, while its outer end may be welded or otherwise secured to the truss members R, R. The truss is thus supported and secured on the column, which, in turn, is reinforced by the gusset plate.

The welds :tor uniting the wing plates to the column and for uniting other parts may be made by fusion depositing suitable metallic material or welding rod fused by high temperature heating means, such as an oxyacetylene flame or an electric arc, as set forth in myprior applications. It will be understood'that while my invention is particularly 7 adapted for tubular columns and shapes, it is also applicable to built-up structural columns and the like, and that the particular shape of the connectors or Wing plates may be varied, and other changes may be made within the scope of this invention.

I claim:

1. The combination of a structural member provided with an opening, an angular wing plate having one leg disposed in said opening and Welded to an edge of the latter, and a second structural member secured to the other leg of said wing plate. I

2. The combination of a column provided with a vertical opening; a wing plate having vertical legs disposed at an angle to one an other, one of such legs having an edge weldedto an edge of said opening; and a structural member secured to the other leg.

3. The combination of a structural member provided with an opening; a pair of spaced wing plates having edges welded to edges of said. opening; and a second structural member secured between said plates.

i. The combination defined in claim 3, wherein said plates are angular and disposed baclr to back.

5. A tubularstructural member provided with an opening in its wall, and a hair of spaced angular wing plates disposed baclr to back and having edges thereof welded to edges of said opening.

6. The combination of a tubular column provided with an opening in its Wall, a pair oi spaced wing plates having an edge of each plate welded to the edge of said opening, and a structural member secured between smd wing plates.

7. The combination of a tubular structural member provided with diametrically opposite openings in its wall, pairs of spaced wing plates secured in said openings, and a structural member extending through said tubular member and secured between said pairs of plates.

In testimony whereof, I ailix my signature.
